1, under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.
2, on the mobile phoneCharging, no restrictions on phone brand. Mobile phone wireless charging is very convenient, just need to power the vehicle, and then put the phone on the charging panel can be achieved. Can car wireless charging be installed? Can be added. You just need to buy a wireless charging module and connect the module's connection port to the vehicle's cigarette lighter through a transfer switch.
2, the car wireless charging what mobile phone can generally as long as the mobile phone has wireless charging function, you can use wireless charging to charge the mobile phone, there is no limit to the brand and model of the mobile phone. As long as there is wireless charging in the car, you can charge the corresponding mobile phone directly on the panelIt's very convenient. To determine whether your phone can be charged wirelessly, put the phone directly on the charging panel, if it cannot be charged, it does not have this function.
3, as long as the mobile phone with wireless charging function, any mobile phone can use wireless charging, will not limit the brand of mobile phone, mobile phone wireless charging is very convenient to use, only need to power the vehicle, and then put the mobile phone on the charging panel, it can be achieved.
4, wireless car charging is a convenient and fast way to charge, any mobile phone with wireless charging function can be used. Just place the phone in the car withoutIn the line charging compartment, the vehicle can start charging after starting, and there is no need to worry about whether the mobile phone brand supports wireless charging. If you want to install wireless charging function in the vehicle, you can achieve by purchasing wireless charging module.
5, [Pacific auto network] Car wireless charging is not what mobile phones can be used. Wireless charging requires the mobile phone to support wireless charging function to use. The power of wireless chargers in different cars varies, so not all phones can be used. A charger that is not suitable for the power of the phone will damage the battery of the phone.
6, as long as the mobile phone model supports wireless chargingThe electric function can be charged on the car wireless charger. If the phone can not support, you can connect a wireless charging patch to the phone, so that the patch is connected to the charging interface of the phone, and then use a data cable from the usb interface of the bracket to connect to the usb in the car, and finally fix the phone on the car charger bracket, adjust the Angle.
1, wireless charger charging speed is slow, there are the following possibilities: 1, wireless chargingElectrical wireless charging power itself is not large. 2, the wireless charging receiver of the mobile phone, the charging current supported is not large. It is recommended to change a high-power wireless charging board, such as a certain meter, which has more than ten coils, although it is not opened at the same time, the effect will be good.
2, low charging efficiency: compared with wired charging, wireless charging efficiency is low. That means it takes longer for users to fully charge. In addition, since wireless charging requires energy conversion between transmit and receive, it may lead to reduced battery life. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This causes users to have to wait longer to complete the charge.
3, low charging efficiency Since it is for mobile phone charging, charging speed is of course the first, even if you can do the application of "wireless", but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
1, if it is assembled, it should be an assembly line may need more than a dozen dozens of people may, of course, now veryMost of them are actually mechanical devices assembled and may only require two or three people to inspect.
2, the steps to set up wireless charging for iPhone 12 are as follows: Confirm that your iPhone 12 supports wireless charging, in general, iphones produced after 2019 support wireless charging. Get a wireless charger to make sure it's compatible with iPhone 12. Connect the wireless charger to a power outlet and connect it to the power supply using the included power cord. Place your iPhone 12 back down on the wireless charger.
3,It also supports fast charging, up to 50% charge in 30 minutes, but requires a power adapter of 20 watts or more. The iphone12 can be charged wirelessly. The iphone12 supports MagSafe wireless charging and Qi wireless charging two charging methods, but the phone does not support wireless reverse charging. The iPhone 12 supports wireless charging.
4, iphone12 series mobile phones support wireless charging function, its wireless charging power is 15W, using MagSafe magnetic charging skills, but also compatible with existing support for its standards of equipment. This is the first time Apple has introduced magnetic charging technology on the iPhone. In order to prevent the deviation of the phone and the coil position when wireless charging, Apple has built a magnet in the iPhone12, as long as it is near the charging plate, the two will be drawn together under the magnetic force.
1, for example, for 6-10 layer memory module PCB design, the selection of 10/20mil (drill/pad) through the hole is better, for some high densityFor smaller size boards, you can also try using 8/18Mil pass holes. Under the current technical conditions, it is difficult to use a smaller size of the hole (when the hole depth exceeds 6 times the diameter of the hole, it is impossible to ensure that the hole wall can be uniformly plated with copper); For the power supply or ground wire hole, you can consider using a larger size to reduce the impedance.
2, control chip: manage the entire wireless charging process, including voltage regulation, power control, communication and other functions. Power amplifier (PA) : Increases signal strength in order to transmit energy efficiently. Oscillators and modulators: Generate high-frequency AC signals for wireless transmissionnumber Coils: Used to generate or receive electromagnetic fields, are a key part of wireless charging.
3, in the range of ravg 0~ 0.08m, the output power increases first and then decreases with the increase of coil turns; In the range of ravg 0.08~ 0.4m, the output power decreases first and then increases and then decreases with the increase of coil turns. For a fixed operating frequency, the quality factor Q mainly depends on the shape and size of the coil and the material used. Standard coil technologies (such as wire winding coils and PCB coils) generally specify quality factor values.
4Wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
5, and 18 requirements must be met. Wireless charging products may have two different modes of operation: charging mode and communication mode. In this case, it is possible to use FCC Part 18 for charging mode and FCC Part 15 for communication mode, but the premise is that the two modes of charging and communication are independent of each other. If the charging mode complies with all the relevant provisions of Part 15, the FCC allows itCharging mode uses Part 15 instead of Part 18.
6, the AP45851 uses a unique "CNS-chip as system" technology to fully integrate a variety of high-performance mixed-signal functions, such as low-power device detection during standby and foreign object detection (FOD) for secure wireless charging. The high level of integration and advanced features help simplify the system design of application engineers, and the periphery is extremely simple, while greatly reducing the difficulty of PCB design.
Assembly and Detail handling Assembling the coil is a key step and I have provided detailed coil Outlines. DXF file, step by step teach you how to print, cut anti-interference tiles, and then embed the wireless transmitter coil perfectly. For the cutting part of the shell, I showed how to use 3D printing technology to transform it, inspired by the Coke can, and shared the fine operation in the grinding process.
The second point, the charging time is too long; Under normal circumstances, the charging bank can be charged for 2 to 3 hoursTo full, like this giant charging treasure, it takes at least two to three days to charge a charge, charging time is so long, it is better to charge yourself directly at home. Therefore, such a bullshit and useless invention completely deviates from the essence of the charging treasure. If you use it, you're paying an IQ tax.
Manual Geng self-made charging treasure may be put into production? In the video of Manual Geng, you can see that the charging treasure made by manual Geng can be used outdoors. And the power bank, handmade by Geng, can power a running TV. In addition, this power bank can also power a washing machine, and canTo ensure the continuous operation of the washing machine.
The large charging treasure made by Geng is a large flat battery pack similar to a battery purchased, and then modified, and the external frame and input and output interfaces are connected, so as to form a charging treasure.
Yes. However, the larger the capacity of the charging bank, the larger the volume and weight, and the more inconvenient it is to carry. Like anything else, it just works. I made a wallet charging bank, capacity 6000 mah, weight less than 120 grams. Enough to fully charge your phone.
No problem. Theoretically any number of parallel connections can be madeSo, the output capacity is the same, but the charge will be slow. The battery is more parallel, and the overall quality is more prone to problems. Because as long as a battery leaks quickly, it will affect the whole.
